Can we use MDM Virtual IP address to access SIO GUI?

Hi Experts,

SIO 2.0.1.2, We are testing all SIO features and noticed SIO MDM master nodes changes and they need to change the IP address of the MDM Master during login to GUI. Can we suggest to use MDM Cluster Virtual IP address to access GUI? Customer is also looking for the cluster logs to see why the MDM master changes nodes. SIO installed on RHEL 7 nodes.

As per SIO 2.0.1.2 release notes:

“MDM Virtual IP address:

The MDM cluster can be assigned a virtual IP address, that will be used for communications between the MDM cluster and SDCs. MDMs are sometimes switched during normal operation of the cluster, and the virtual IP address will always be mapped to the active MDM. The virtual IP address on the MDM cluster ensures that all SDCs remain connected to the MDM, even after the physical server is replaced, thus simplifying maintenance procedures and preventing the need to reconfigure all SDCs in a system”.

What are the scenario’s MDMs are switched?

As per user guide:

Connection and disconnection information

You can check at any time to which ScaleIO system IP address your GUI is connected

using the following methods:

1. View the IP address displayed on the top left side of the GUI window.
2. Hover your mouse pointer over the Management tile on the Dashboard. A tooltip

displays connection information for the nodes in the MDM cluster, and the

management IP addresses

If your GUI loses its connection with the MDM, the window display is dimmed, and

a notification dialog box is displayed

Thanks in advance
